Confiança

Seus contratos continuam seus.

Os fatos que podemos sustentar hoje: quem pode ver uma sala, o que Lex faz com o texto e como nos avisar que erramos.

Who can see a shared contract room

A shared contract room is the page both sides use for one deal. Only the two sides in a room can see that contract: the people you invite, and the people they add. Nobody else can open it. It is never listed or searchable.

The other side never pays and never needs an account. You copy one share link; they open it free, with no account. Both sides negotiate through that one link. Each side’s Lex, notes and playbook stay on that side. The other side never sees them.

How the paper works: how to write a contract, NDAs explained, when a client redlines. Product statements: facts. Plans: pricing.

What encryption in transit and at rest means

Encrypted in transit means the contract is protected while it moves between your browser and the service. Connections use HTTPS.

Encrypted at rest means the stored copy is protected on disk. The database, files and backups are encrypted on disk.

Versions, e-sign and the signing record

Every version is kept. Nothing is edited silently. Each change shows who proposed it and when it was accepted. A redline is a proposed edit, not a signed change. Accepting a clause is not signing.

When the words are agreed, both sides e-sign one frozen version. An is any electronic way of showing agreement, such as a typed name. Signatures attach to the exact words signed. Later edits are a new version; earlier signatures stay with the words they signed.

The signing record is the downloadable record of that e-signature — the audit trail of who signed the frozen wording. Both sides get the signed contract and its signing record. Keep it for as long as you like.

The executed version is the signed, frozen text that is the deal. Drafts, and comments are not. A counterpart is a signed copy of the same wording.

Como tratamos o texto dos contratos

De-identified content means text with identifying details removed. The rule for each plan is the published data-use line:

Free and Plus may use de-identified content from your own side of the deal to improve Lex, with an opt-out in Settings. Pro, Team and Enterprise content is never used, and the other side's content is never used.

The same line is on facts and pricing.

O que Lex faz e não faz

Lex drafts the contract from a description of the deal, usually one sentence. Plain English explains each clause. The legal wording governs.

Lex drafts and explains. It never sends, accepts or signs. A person always does that. Plain English is an explanation; the legal wording governs.

Lex não é advogado. Pode deixar passar um risco, inventar uma cláusula incomum ou explicar mal uma cláusula. Leia a redação jurídica antes de enviar ou assinar. Se o acordo for incomum ou de alto risco, peça a um advogado para olhar — veja /lawyers.

Perguntas frequentes

Quem pode ver uma sala?

Só os dois lados: as pessoas que você convida e as que elas adicionam. As salas não são listadas nem pesquisáveis. Toda versão é guardada e as assinaturas ficam presas ao texto exato que foi assinado.

O texto do meu contrato treina Lex?

O Free e o Plus podem usar conteúdo desidentificado do seu lado para melhorar Lex, com opção de recusar. O conteúdo do Pro, do Team e do Enterprise nunca é usado, e o conteúdo do outro lado também não.

O que Lex não faz?

Lex redige e explica. Nunca envia, aceita nem assina. A linguagem simples é uma explicação; o texto jurídico é o que vale.

Como as conexões são protegidas?

As conexões usam HTTPS. Os dados são criptografados em trânsito e em repouso.

Como aviso sobre um erro ou um problema de segurança?

Correções: escreva para hello@contracts.io com a URL e o que deve mudar. Segurança: escreva para hello@contracts.io.

Is contracts.io safe for contracts?

A contract is only visible to the two sides: the people you invite, and the people they add. It is never listed or searchable. Connections use HTTPS. Data is encrypted in transit and at rest. Every version is kept. Signatures attach to the exact words signed. Both sides can download the signed contract and its signing record.

What is a signing record?

The downloadable record of the e-signature on a frozen version. Both sides get the signed contract and its signing record, and can keep it for as long as they like. Every version is kept, and signatures attach to the exact words signed.

Are e-signatures valid?

In England and Wales, an electronic signature is admissible in evidence and capable of executing a document where the signer intends to authenticate it and any formalities are met. Under the federal ESIGN Act, electronic form alone is not a reason to deny legal effect. The sourced lines are listed on the facts page.
